Question

I am using Hibernate 4, Spring 3 and JSF 2.0 and Weblogic 10.3.6
I have the following in DAO class

        CriteriaBuilder cb = entityManager.getCriteriaBuilder();
        CriteriaQuery<Request> c = cb.createQuery(Request.class);

When I run my application I am getting the following exception.

javax.persistence.EntityManager.getCriteriaBuilder()Ljavax/persistence/criteria
/CriteriaBuilder;

java.lang.NoSuchMethodError: 
javax.persistence.EntityManager.getCriteriaBuilder()Ljavax/persistence/criteria
    /CriteriaBuilder;
    at net.test.request.dao.RequestDAOImpl.getRequest(RequestDAOImpl.java:51)

I did not use JPA1 jars, however I am still getting this exception. Not able to figure how to get rid of this exception. Any help is highly appreciable.

Thanks

Answer 1

The method EntityManager.getCriteriaBuilder is a part of JPA 2 (which is part of Java EE 6), which is not provided and/or turned on by default in WebLogic 10.

Here is a link http://docs.oracle.com/cd/E17904_01/web.1111/e13720/using_toplink.htm which provides instructions that may fix your problem. If not, you’ll need to start googling “weblogic 10 jpa 2” and see if you can find a solution that works for you.

If none of these solutions work, your last resort will be to redesign your application to only use JPA 1 methods. To use JPA 1 you must limit yourself to the classes and interfaces defined here: http://docs.oracle.com/javaee/5/api/javax/persistence/package-summary.html

[update]

Or – since you are using Hibernate anyways, don’t rely so much on JPA classes. Use hibernate specific classes instead. Hibernate has had criteria since 3.x. Instead of an EntityManager you create a Hibernate session factory. Then you can do:

import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;

...

Session session = sessionFactory.openSession();
Criteria crit = session.createCriteria(Person.class);

Your code is now locked into using Hibernate as your persistence provider. In my case we always use Hibernate so it’s not a real problem. This is a question you have to decide for yourself. If your application can tolerate being locked into Hibernate, this should give you the functionality you need while still running on WebLogic.
